PERMUTATlON-LOCK.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed August 15,1905. Serial No. 274,317.

To @ZZ zoll/07m it ntay con/cern:

Be it known that I, CHRISTIANUS ANTO- NIUs FRANcIsCUs ANRCHTE, yof 56 Jacob van Campen straat, Amsterdam, Netherlands, have invented certain new and useful Improvements in Permutation Locks, of which the following is a specification.

This invention relates to permutation locks and fastenings, such as are well known, and has for its object to construct such locks and fastenings in a novel manner, whereby to render them suitable for use with articles to which they have not hitherto been fitted in a satisfactory manner, and also by a particular construction to increase their strength for resisting rough methods of tampering with same.

In the accompanying drawings, Figures l and 2 are respectively plan andside /elevation of a permutation lock or fastening suitable for wallets, trunks, and like articles in which a flap or hasp is commonly used. Fig. 3 is a sectional .plan with the hasp part removed for clearness, and Fig. 4 is a longitudinal section (With the hasp part in position) drawn to a larger scale. In these figures the permutation-lock is shown in combination with a spring-catch fastening of known construction. Fig. 5 is a longitudinal section of a permutation-lock suitable for hand-bags, kit-bags, boxes, and other articles in which the edges or faces of two members are brought together abutting against one another. Fig. 6 is a longitudinal section, and Fig. 7 is a cross-section on the line :t of Fig. 6, of a permutation-lock suitable for drawers, doors, and other similar articles. Fig. S is a longitudinal section of a modification.

Referring to Figs. 1 to 4, al is the case of the lock. t is the fiap or hasp. c is a springn controlled sliding catch-plate, the ends c of which are adapted to engage slotted or notched studs c2, secured to the hasp part b. d d2 are permutation-disks which are mounted upon slotted tubular axles e e, one of which disks and axles is carried by a vertical plate a in the case of a, and the other, d2, by a plate t', attached to the hasp part b. g is the key-bolt, which slides in the tubular axles e e, but cannot rotate therein by reason of the projecting bits g. Each disk has an annular recess (ZX therein, with which the bits g of the key-bolt g engage to prevent the bolt from being withdrawn,` and a slot d,

communicating with said recess, permits the passage of the bit g when the bolt is withdrawn. 'As shown in Fig. 4, thedisks d d2 are in position; to allow of the key-bolt g being vwithdrawn fromthe hasp part 6,' and upon `witl'idrawing the lcatch-plate c, thereby dise'ngaging the studs c2; the hasp part is free for removal from the lock. In this drawing, Fig. 4, the withdrawal ofthe key-bolt g'also withdraws the catch-plate c by the contact of their respective finger pieces or knobs.

In Fig. 5 the lock is shown fitted to a handbag, two disks d d and axles e e being carried by one part or frame h and the other disk d2 and axle e by the other frame h. By way of example the axle e is fixed in a projecting plate h2, fixed to or formed out of the frame 7L. The axle e (at the left of the figure) is fixed to a plate h3, projecting from the frame h, the axle e (at the right of the figure) being formed out of the substance of the frame. The key-bolt g is provided with a suitable external handle or knob g2, the stem of which works through a slot h4 in the frame h. The amount of movement of the key-bolt g necessary to disengage the disk d2 is indicated by the dotted lines. The plates h2 h3 are each formed with a key way or slot hX to permit the passage of the bits g of the key-bolt g.

Figs. 6 and 7 show a permutation-lock of my improved construction tted to a door. The plate i of the case is formed with two or more carrier-plates i, in which the slotted tubular axle e is fixed and in which slots are formed to accommodate a locking-bolt 7c. The key-bolt gis fixed to a stump c, formed on the end of the bolt 7c, and is operated by an external handle k2, the stem of which passes through the slot *L2 and is fixed to the stump lc. The substance of the door Zis'cut away at l to accommodate the carrier-plates i', which may be of dovetail shape, as shown, so that the lock is attached by sliding the same into the recess Z from the edge of the door and securing the same by screws passed through the plate i. A plate m is sometimes fitted (or it may form part of the plate i) to give the edge a finished appearance. n is a keeper-plate' fixed to the door post or jamb f/L, a socket n2 being formed therein to accommodate the bolt k, as shown.

In some cases, as shown in Fig. 8, the keeper plate or box n may be provided with a slotted axle e and disk d2, mostly sunk with- IOO in the door-post, in which case the key-bolt g is extended to engage the same in the inanner already described. The permutationdisks are provided with letters, and when a certain letter on one disk is in alinenient with certain letters on the other disks the slots d are in alinernent7 thus affording a free passage lor the bits g of the bolt.

I claim- 1. A permutation-lock comprising a casing and a keeper, independent slotted hollow' axles in said parts, a slotted permutationdisk mounted on each axle and a sliding keybolt passing through the axles and interlocking with the said disks.

2. A permutation-lock comprising a casing and a keeper, independent slotted axles in said parts, a slotted permutationdisk mountedvon each axle and a sliding key-bolt carried by one of the axles and interlocking with the said disks and a looking-bolt integral with said key-bolt and parallel therewith.

3. A permutation-lock comprising a casing and a keeper, slotted hollow axles carried by said parts, said axles extending longitudinally, a slotted permutation-disk mounted to rotate on each axle, a sliding bolt passing through the axles and( lugs on said bolt passing through the slots in the axles and interlocking with the disks.

In witness whereof I have hereunto set my hand in the presence oftwo witnesses.
